Answer:
I know a word of letters three. Add two and fewer there will be. What is the word?
The dirtier I get, the whiter I am. What am I?
I cause involuntary movements in your vehicle
I hatch without food
I have to be broken before I can be used
I am a food with 5 letters. If you remove the first letter I am a form of energy. Remove two and I'm needed to live. Scramble the last 3 and you can drink me down.
